The son of a former Split Enz drummer is under investigation by Australian police for internet stalking and is said to be "inciting hatred" online from his New Zealand home.
Tristan Barker, 18, is wanted for questioning by Melbourne police for encouraging his alleged 300,000 Facebook followers to ridicule people, including murder victims and some who have committed suicide as a result of online bullying. But Melbourne police are unable to interview him because he is back in Rotorua living with his dad, Michael Barker, a former drummer from bands Split Enz and the John Butler Trio.
In one of his posts, about the Colorado movie theatre shootings last year that claimed 12 lives, Tristan Barker called it a "social experiment".
"I don't give a f*** about the victims, I don't give a f*** about their families, I don't care, no one should care," he wrote on Facebook. He went on to request Americans "end themselves".
"I wanted to see if you could create disgust," he said this week.
